What's the best Android app for playing Spider Solitaire with a smooth, non-frustrating hint system?

Spider Solitaire is a strong contender for players who want guidance without the game playing itself. Its primary strength lies in a hint system designed to suggest potential moves by subtly highlighting cards or columns, rather than automatically executing plays. This approach is particularly useful for newcomers learning the intricacies of Spider Solitaire's eight-deck layout, or for seasoned players momentarily stuck on a complex tableau. The app offers multiple difficulty levels, from one suit to the challenging four suits, allowing the hint utility to scale with the user's needs. While the core gameplay is polished with smooth animations and clear card faces, some users note that the ad-supported model can occasionally interrupt the flow with a video ad after a certain number of games or hints used. However, reviews consistently highlight that these ads are generally brief and do not detract significantly from the experience. The undo function is generous, working in tandem with the hints to create a low-pressure environment for strategic experimentation. For anyone seeking a classic card game that assists but doesn't automate the thinking process, this implementation strikes a practical balance.
